It receives API configuration dynamically through a webhook, sends the request to the primary API, and checks the response status. If the request fails, the workflow waits briefly and retries the request. If the retry also fails, it automatically switches to the backup API provider. Successful responses are returned immediately using webhook response nodes, while complete failures generate structured error responses. This architecture improves reliability, reduces downtime, and allows the workflow to work with any API dynamically.\n\n**Setup steps**\n\nConfigure the webhook URL and activate the workflow. Pass the primary API URL, backup API URL, HTTP method, and retry count in the webhook request body. Update timeout settings if required and optionally add headers or request body forwarding for POST APIs. Test the workflow using success, failure, timeout, and backup scenarios to verify recovery behavior. This workflow can be extended further with Slack alerts, logging, AI-based root cause analysis, and database monitoring for production systems."

About this workflow
This workflow exposes a webhook that forwards a request to a primary API, retries once after a short delay if it fails, and then fails over to a backup API, returning a structured JSON success or error response to the caller. Receives a POST request on an n8n webhook with the…
